For the fourth summer, FLOW, Brussel’s only open-air swimming pool, is open to the public.
Do you fancy splashing around in the water on a hot summer’s day in Brussels? Would you like somewhere clean and safe to take the children to cool off? (Yes, I know all this depends on the weather improving, but let’s remain hopeful!). Then you need to book some time at FLOW in Brussels.

FLOW: The only public outdoor pool in Brussels
With its dimensions of 17 x 7 meters and located near to the canal in Anderlecht, FLOW is the only outdoor swimming opportunity for everyone in Brussels. On the sun decks you can warm up after swimming, enjoy the atmosphere around the pool, and get a cool drink from the kiosk. You can book a time slot two days in advance, either online or at the pool. Prior reservation is necessary to guarantee a pleasant and safe experience for all swimmers. Booking for free swimming classes is also possible.

Open all year round
The FLOW swimming pool near to the canal in Anderlecht is open every day throughout the summer. What’s more, unlike in previous years, FLOW will no longer close once the summer season is over: it will welcome visitors all year round. And yes, that includes the winter!

New this year: FLOW CHAUD sauna
New for 2024 is the FLOW CHAUD sauna. This facility is expected to be very popular, especially considering the traditionally fickle Belgian weather, when a hot sauna can come in very handy! The sauna will also be open in autumn and winter too, although with more limited opening times.

A conscious decision was made to heat the sauna electrically in order for FLOW to remain a pioneer in terms of sustainability. The entire FLOW site, from the water filters to the sauna, is powered by locally generated green electricity, via energy platform Bolt. The energy is generated in Gougnies, Wallonia, at a hydroelectricity plant.
More than just swimming
FLOW is also much more than simply swimming. It offers a full program of other activities such as yoga, qi gong, and aquagym classes, morning group swims, women’s-only swimming slots, and a varied program of music and art performances. You can experience this while swimming and in the evening.

Lovely in this heat ?
One has to remain defiantly optimistic. Despite the evidence to the contrary.
Ha yes! And honestly, in my youth I remember having more often than not grey days in summer.
I shiver at the thought of entering the pool during winter.
Don’t worry Rosaliene, I will be right behind you when you step in! 🙂

What a great facility. Is the water heated?
